The complete mitochondrial genome and phylogenetic analysis of Matuta planipes (Decapoda: Brachyura: Matutidae)

The complete mitochondrial genome of Matuta victor (Decapoda: Matutidae) from Beibu Bay

The true crabs (Brachyura) including Calappidea are one of the most diverse groups of Decapod crustaceans However, despite their great diversity and commercial importance, phylogenetic and classification relationships within Calappidea are still complicated and controversial. In this study, we report the first complete mitochondrial genome of Matuta victos. The mitogenome has 17,782 base pairs (70.1% A + T content) and is made up of a total of 37 genes (13 protein-coding, 22 transfer RNAs and two ribosomal RNAs), plus a putative control region. This study will provide useful molecular resources for clarifying evolutionary and phylogenetic confusion within Calappidea.

Characterization of the complete mitochondrial genome of Xanthid crab, Atergatis integerrimus from China (Decapoda: Brachyura) and its phylogenetic analysis

The complete mitochondrial genome sequence of Atergatis integerrimus from China has been amplified and sequenced in this study. The mitogenome assembly was found to be 15,924 bp in length with base composition of A (32.88%), G (10.58%), C (20.87%), T (35.66%), A + T (68.54%), and G + C (31.46%). It contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and a control region. The phylogenetic position was constructed and the A. integerrimus was closely clustered with Pseudocarcinus gigas and Leptodius sanguineus. The complete mitochondrial genome sequence would be useful for further understanding the evolution of A. integerrimus.
